font quality / gamma correction

I need help to get the BEST, sharpest, most crisp font quality (including proper size) in Ubuntu Feisty Fawn, to match Windows as much as possible (Vista). I've tried so much, no matter what I've done I cannot get the fonts as crisp as Windows at all.

I installed 32bit Ubuntu Feisty Fawn and by default, the resolution was properly set to 1280x800 (widescreen) on 60Hz refresh. Do I need to install/enable 915resolution?
